Looking for a Nexus device at a brick and mortar location? Then you may be in luck. Google just unveiled the Nexus Store Locator tool, and it's pretty simple: type in your address, find a Nexus device retailer. You can choose from the Nexus 4 or Nexus 7. Right now the only Nexus 4 retailer in the US is T-Mobile, so it's really just a T-Mobile store locator for the moment if you're looking for one of those.
